Description

Technical Field

[0001] This utility model relates to the technical field of air magnetic levitation centrifugal blowers, specifically to an adjustable air intake mechanism for an air magnetic levitation centrifugal blower. Background Technology

[0002] Air magnetic levitation centrifugal blowers are a commonly used type of energy-saving blower, characterized by high operating efficiency, low noise, and low operating costs. Existing air magnetic levitation centrifugal blowers use an inlet duct for air intake and an outlet duct for air exhaust. The air intake and exhaust volumes are adjusted synchronously, without independent adjustment of the intake volume. This results in poor flexibility in air intake volume adjustment, thus affecting the overall flexibility of the air magnetic levitation centrifugal blower's use. Utility Model Content

[0003] To address the shortcomings of existing technologies, the present invention aims to provide an adjustable air intake mechanism for an air magnetic levitation centrifugal blower.

[0004] To solve the above-mentioned technical problems, this utility model achieves the following solution:

[0005] This utility model provides an adjustable air intake mechanism for an air magnetic levitation centrifugal blower, including an air magnetic levitation centrifugal blower, wherein the air intake of the air magnetic levitation centrifugal blower is fixedly connected to an air intake pipe, and an air intake adjustment mechanism is installed on the air intake pipe.

[0006] The air intake volume adjustment mechanism includes an internally threaded mounting tube threaded onto the air intake pipe. Two rotating holes are symmetrically opened on the wall of the internally threaded mounting tube. A rotating shaft is rotatably fitted into each of the two rotating holes. A circular adjusting baffle is fixedly connected between the two rotating shafts. The diameter of the circular adjusting baffle is the same as the inner diameter of the internally threaded mounting tube. A U-shaped plate is fixedly connected to the upper side of the internally threaded mounting tube. An electric actuator is fixedly connected to the vertical side wall of the U-shaped plate. A connecting plate is fixedly connected to the output end of the electric actuator. A rack is fixedly connected to the connecting plate. An mounting shaft is fixedly connected to the upper end of the rotating shaft located on the upper side. A gear that meshes with the rack is fixedly fitted onto the mounting shaft.

[0007] Furthermore, a push rod is fixedly connected to the lower side of the internally threaded mounting tube, and the push rod wall is fixedly sleeved with an anti-slip sleeve.

[0008] Furthermore, a shaft hole is provided on the upper side of the U-shaped plate, and the upper end of the rotating shaft passes through the shaft hole through the U-shaped plate. The rotating shaft is rotatably connected to the wall of the shaft hole through a bearing.

[0009] Furthermore, a support plate is fixedly connected to the vertical side wall of the U-shaped plate, the electric push rod is fixedly connected to the upper side of the support plate, and a reinforcing plate is fixedly connected between the lower side wall of the support plate and the outer wall of the internally threaded mounting pipe.

[0010] Furthermore, a straight rail is fixedly connected to the vertical sidewall of the U-shaped plate, and a guide groove corresponding to the straight rail is opened on the vertical sidewall of the connecting plate, through which the straight rail passes through the connecting plate.

[0011] Furthermore, the outer wall of the anti-slip sleeve is provided with multiple anti-slip grooves, which are evenly distributed on the anti-slip sleeve.

[0012] Furthermore, the left side wall of the air magnetic levitation centrifugal blower is evenly provided with multiple dustproof and heat dissipation vents.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, through its air intake volume adjustment mechanism, allows for independent adjustment of the air intake volume. The control electric actuator drives the connecting plate to move, which in turn moves the rack, which in turn rotates the gear. The gear then rotates the mounting shaft, which in turn rotates the rotating shaft. This rotating shaft causes a circular adjusting baffle to deflect within the internally threaded mounting tube, thereby adjusting the angle between the circular adjusting baffle and the inner wall of the internally threaded mounting tube. The larger the gap, the greater the air intake volume. This allows for quick, convenient, and flexible adjustment of the air intake volume of the air magnetic levitation centrifugal blower, effectively improving the flexibility of its use.

Obviously, the embodiments described in this utility model are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Example 1: The specific structure of this utility model is as follows:

[0025] Please refer to the appendix. Figure 1-6 This utility model provides an adjustable air intake mechanism for an air magnetic levitation centrifugal blower, including an air magnetic levitation centrifugal blower 1, wherein the air intake of the air magnetic levitation centrifugal blower 1 is fixedly connected to an air intake pipe 2, and an air intake adjustment mechanism 3 is installed on the air intake pipe 2.

[0026] The air intake volume adjustment mechanism 3 includes an internally threaded mounting tube 4 threaded onto the air intake pipe 2. The internally threaded mounting tube 4 has two symmetrically opened rotating holes 5 on its wall. A rotating shaft 6 is rotatably fitted into each of the two rotating holes 5. A circular adjusting baffle 7 is fixedly connected between the two rotating shafts 6. The diameter of the circular adjusting baffle 7 is the same as the inner diameter of the internally threaded mounting tube 4. A U-shaped plate 8 is fixedly connected to the upper side of the internally threaded mounting tube 4. An electric actuator 9 is fixedly connected to the vertical side wall of the U-shaped plate 8. A connecting plate 10 is fixedly connected to the output end of the electric actuator 9. A rack 11 is fixedly connected to the connecting plate 10. An mounting shaft 12 is fixedly connected to the upper end of the rotating shaft 6 located on the upper side. A gear 13 that meshes with the rack 11 is fixedly fitted onto the mounting shaft 12.

[0027] In the above embodiment, when the air intake volume is adjusted independently, the electric actuator 9 drives the connecting plate 10 to move, the connecting plate 10 drives the rack 11 to move, the rack 11 drives the gear 13 to rotate, the gear 13 drives the mounting shaft 12 to rotate, the mounting shaft 12 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the circular adjusting baffle 7 to deflect within the internally threaded mounting tube 4, thereby adjusting the angle between the circular adjusting baffle 7 and the inner wall of the internally threaded mounting tube 4, thereby adjusting the gap between the circular adjusting baffle 7 and the inner wall of the internally threaded mounting tube 4. The larger the gap, the larger the air intake volume, thus enabling quick, convenient, and flexible adjustment of the air intake volume of the air magnetic levitation centrifugal blower 1. This allows for independent adjustment of the air intake volume of the air magnetic levitation centrifugal blower 1, effectively improving the flexibility of using the air magnetic levitation centrifugal blower 1.

[0028] A push rod 14 is fixedly connected to the lower side of the internally threaded mounting tube 4. The push rod 14 is fixedly sleeved with an anti-slip sleeve 15. By pushing the push rod 14, the internally threaded mounting tube 4 can be rotated, which improves the convenience of disassembling and assembling the internally threaded mounting tube 4. The anti-slip sleeve 15 can improve the comfort of using the push rod 14.

[0029] The upper side of the U-shaped plate 8 is provided with a shaft hole 16. The upper end of the rotating shaft 6 passes through the U-shaped plate 8 through the shaft hole 16. The rotating shaft 6 is rotatably connected to the hole wall of the shaft hole 16 through a bearing, which can improve the rotation stability of the rotating shaft 6.

[0030] A support plate 17 is fixedly connected to the vertical side wall of the U-shaped plate 8. The electric actuator 9 is fixedly connected to the upper side of the support plate 17. A reinforcing plate 18 is fixedly connected between the lower side wall of the support plate 17 and the outer wall of the internal threaded mounting pipe 4. The support plate 17 and the reinforcing plate 18 cooperate with each other to support and reinforce the electric actuator 9, thereby improving the stability of the electric actuator 9.

[0031] A straight rail 19 is fixedly connected to the vertical side wall of the U-shaped plate 8. A guide groove 20 corresponding to the straight rail 19 is opened on the vertical side wall of the connecting plate 10. The straight rail 19 passes through the connecting plate 10 through the guide groove 20. The straight rail 19 and the guide groove 20 cooperate with each other to limit and guide the connecting plate 10 and the rack 11, effectively improving the stability of the rack 11 movement and improving the accuracy of the air intake adjustment mechanism 3.

[0032] The outer wall of the anti-slip sleeve 15 is provided with a plurality of anti-slip grooves 21, which are evenly distributed on the anti-slip sleeve 15. The plurality of anti-slip grooves 21 can improve the anti-slip effect of the anti-slip sleeve 15.

[0033] The left side wall of the air magnetic levitation centrifugal blower 1 is evenly provided with multiple dustproof heat dissipation vents 22. The dustproof heat dissipation vents 22 can improve the heat dissipation efficiency of the air magnetic levitation centrifugal blower 1 and improve the operational stability of the air magnetic levitation centrifugal blower 1.

[0034] Working principle: When the air intake volume is adjusted independently, the control electric actuator 9 drives the connecting plate 10 to move. The connecting plate 10 drives the rack 11 to move, the rack 11 drives the gear 13 to rotate, the gear 13 drives the mounting shaft 12 to rotate, the mounting shaft 12 drives the rotating shaft 6 to rotate, and the rotating shaft 6 drives the circular adjusting baffle 7 to deflect inside the internal thread mounting tube 4. This allows adjustment of the angle between the circular adjusting baffle 7 and the inner wall of the internal thread mounting tube 4, thereby adjusting the gap between the circular adjusting baffle 7 and the inner wall of the internal thread mounting tube 4. The larger the gap, the larger the air intake volume. This allows for quick, convenient, and flexible adjustment of the air intake volume of the air magnetic levitation centrifugal blower 1, enabling independent adjustment of the air intake volume of the air magnetic levitation centrifugal blower 1 and effectively improving the flexibility of its use.
